It looks like some Nokia Lumia owners are going to be in for a 4K treat. It doesn't seem like it is a continuous recording mode but if you can do 10 second clips that's all I need.

Nice to see a phone company expanding video features through a free firmware update. It's amazing that a phone that launched for less than $100 on contract last year will get 4k for free. I wish Apple would take a page from Microsoft's book instead of making people pay through the nose for basic features tons of other phones have. I mean am I to understand you have to pay $300 ON CONTRACT just to get the only iphone that has an HD screen? Terrible. And still no microSD expansion slot?
